Growing and Guiding Embryonic Stem Cells

Description

Embryonic stem (ES) cell culture depends on keeping cells undifferentiated. In this state, they can self-renew and remain pluripotent, which means they can still form many different cell types.

This page explains the basic principles of ES cell culture and shows a general method for growing and p...

胚胎干细胞(ES 细胞)具有一些独特的特性,使其区别于普通的成体细胞。因此,科学家们设计了特殊的培养技术,以维持或利用这些特性。在适当培养条件下,ES 细胞能够无限分裂,实现自我增殖。同时,通过改变培养条件,ES 细胞可被诱导分化为人体内几乎任何类型的细胞;这种能力被称为“多能性”。

在本视频中,您将学习如何培养和传代 ES 细胞以保持其独特特性,如何诱导 ES 细胞分化形成特定细胞类型,以及当前研究人员如何应用并改进 ES 细胞的培养与分化技术。

在详细介绍胚胎干细胞(ES细胞)培养的操作步骤之前,首先需要了解哪些因素会抑制或促进ES细胞的分化。为了使ES细...
